染色体

Cases were considered as heterozygous if PCR amplification of undigested DNA showed two major bands with equal intensity. Cases with only one major band were homozygous for HUMARA and thus uninformative.

2·讨论一、克隆状态分析与HUMARA分析在胚胎发育早期，女性体细胞的两条X染色体中，随机地有一条发生失活，因此正常女性组织的X染色体失活方式为随机性。

The promoter region of hsp genes often contain the binding sequences of a series trans-factors which induce the basic transcription, such as SP1, CAAT and ATF, and with some heat shock elements in their 5\' upstream.

Wu于1980年在研究活化染色体的结构改变以及活化染色体对基因表达调控作用的影响过程中，首次在果蝇的hsp70基因上发现了多个DNaseI高敏感位点。

In women, X chromosomes pair; in men, the X and Y chromosome pair.

在妇女， X染色体配对，在男子， X和Y染色体的配对。

Now some of these may be on the X chromosome,.

现在其中一些也许存在于其体内的 X 染色体上。妇女的第二个 X 染色体可以补偿。

The father has a normal X gene on the X chromosome and a normal Y chromosome.

父亲有一个正常 X 基因在 X 染色体和一条正常 Y 染色体。

Men may have an extra X chromosome or two on top of their normal XY combination.

男性可能会在正常的XY染色体组合上多出一根或两根X染色体。

The positive rate of Y chromosome of mice in Groups 2-6 was 100%.

第2～6组小鼠染色体核型分析显示Y染色体阳性率为100％。

But this prohibition has caused most of the genes on the Y chromosome to decay for lack of fitness.

这种禁止也导致Y 染色体上的大多数基因退化，在其它的基因组上，被损坏的基因可以通过与另外的染色体交换而除去。

Because this basis and 18 contrast of chromosome will diagnose big Y chromosome, should have a more exact level.

因此根据和18号染色体的对比来诊断大Y染色体，应该有一个更为精确的标准。

These genes appear most frequently on chromosome 12 but rarely on chromosome 21 and Y.

这些基因在12号染色体上出现频率最高，而在21号和Y染色体上很少出现。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
